In this work, it is described a newly featured massive Vapor‐Liquid‐Solid deposition process, in which the yield of conventional VLS reaction is increased in several orders of magnitude. Al 2 O 3 fibers and crystals are here obtained from aluminum and silica in Ar atmospheres containing metal vapors and at low partial pressures of H 2 O. The relationship between the controlled incorporation of H 2 O(g) and the observed features of the alumina crystals (and of the VLS itself) is assessed in terms of the respective Al‐Al 2 O 3 and Si‐SiO 2 volatility diagrams.
